1. What is MAIO?
Ans: Mobile Application Index offset.
2. what is EIRP?
Ans: Effective Isotropic Radiation Power.
Pr(d)=PtGtGr lamda/(4pi)^2d^2L
3. What is the difference between FER and BER? what is timing advance?
Ans: FER: frame Erasure rate, it measure the speech quality after activation of RXQUAL. for 8 kbit data rate its allow 3% and for 13 kbit its allow 5%.
4. what is TEMS?
Ans: Telecommunication Expense managment system. it is used for Radio network optimization. it is primary tools.
5. describe the different coding data rate of GPRS?
Ans: there are four coding scheme for GPRS. these are CS1, CS2,CS3,CS4. data rate is 9kbit,12.05 kbit, 15.6 kbit, 21kbit respectively.
6. a subscriber make three call 4 mins, 3 mins, 5 mins in a hour then what is traffic intensity in Erlang?
